9 of the Best AI Tools for Software Developers in 2025

2025 is here, so I think it’s the perfect time for us to take stock of the very best AI tools for developers that we can use to get ahead in the new year and improve our development processes.

So many new artificial intelligence (AI) tools have been released this year as large language models like ChatGPT have gathered meteoric pace. So I’ve picked out the very best tools every software developer should know about and have a play with.

1. ClickUp – The AI-First Productivity Engine for Software Teams

2. Cody AI: Advanced Code Assistant

Cody AI accelerates our process of writing code.

If you’re not using an AI coding assistant, you’re being left behind. (And if you’re still using GitHub Copilot, that’s probably still true!) They save time, and can help you out in all kinds of ways from suggesting code to automatically generating entire files through their natural language processing capabilities, and more.

This list has a few AI coding assistants and Cody is the first. By deeply analyzing your existing code, documentation, and code graph, Cody can give you speedy and insightful responses to queries about your codebase. 

Key features

• Search and analyse your codebase with natural language prompts
• Precise code navigation 
• Language translation for code
• Detailed code analysis and debugging assistance

Try it free? Yes, most features are available for free with a generous rate limit.

My view – For engineers dealing with expansive codebases, Cody is a great option. It enables developersunderstand what we’re looking at, write better code faster, and ultimately allows more time for actual coding.

3. Tabnine: Established Code Assistant

Tabnine is a reliable, security-conscious AI code assistant that it’s easier to get approval for.

Now built on GPT-3.5 and having evolved over five years, Tabnine is transparent, compliant, and offers a plethora of valuable features to help us devs write code faster.

Because it’s been knocking around for a while, they’ve had time to deliver strong, trustworthy security and compliance credentials that your managers will be reassured by.

It’s not the most powerful AI coding assistant on this list, but it might be worth the trade-off to be allowed to use it!

Key features

• Reliable and secure coding assistance
• Comprehensive training data transparency
• Local out-of-the-box execution

Try it free? Yes, but it’s very limited – you just get short code completions. Whole-line and function completions are available for $12/mo/user at the time of writing.

My view – Tabnine is perfect for devs working for teams that are prioritising security and dependability over the latest tech novelties. Like its competitors, it integrates with popular IDEs (integrated development environments) seamlessly.

4. Mutable AI: Powerful Code Assistant

Mutable AI accelerates software development using AI.

Aiming to eliminate the need for repetitive boilerplate code and unnecessary searches, Mutable ensures faster and better code delivery running on proprietary AI.

It’s the youngest code assistant on this list but perhaps one of the most high-tech and performant ones, with a rapid pace of development even compared to competitors. 

Key features

• Codebase chat and semantic search
• Multi-file AI edits
• Repository intelligence for bug tracking and more

Try it free? Yes, at the time of writing you get a generous number of codebase chat and search queries and file edit calls for you to give it a spin. More features unlock at $25/mo/user and $50/mo/user

My view – Mutable stands out for its superior code completion capabilities, especially over multiple files.

5. Codium AI: Test-Writing Assistant

Codium ensures your code functions as intended.

By suggesting tests during coding, Codium helps us avoid pesky errors and bugs. As you code, the AI suggests intelligent test ideas, and can write them for you. Plus, it can show you how your code changes impact the wider system. 

Key features

• Intelligent test suggestions – just commit
• Insight into code behavior
• Recommendations based on code, docstrings, and comments

Try it free? Yes, you can try all the key features for free, but you have to pay $19/mo/user at the time of writing to add tests to existing test suites, get enhanced security and a few other features.

My view – Maybe you love writing test suites, but if you’re like the average dev, it probably isn’t in your top 3 activities. And introducing a big bug by accident can probably ruin your day, and maybe your evening. Codium helps us ship with more confidence, without the hassle of painstakingly writing tests.
